Remove “Ads By DealNinja” adware (Virus Removal Guide)

DealNinja is an adware program, that displays pop-up ads and advertisements on web pages that you visit. The “Ads by DealNinja” advertisements will be shown as boxes containing various coupons that are available, as underlined keywords, pop-up ads or advertising banners.

What is DealNinja?

DealNinja is advertised as a program that displays coupons for sites you are visiting and competitive prices when you are viewing product pages at sites like Amazon or eBay. Though this may sound like a useful service, the DealNinja program can be intrusive and will display ads whether you want them to or not.
When installed, the DealNinja browser extension will display advertising banners, pop-up advertisements and in-text ads, stating that they are brought to you by “DealNinja”. The DealNinja Ads will have different text under the pop-up: “Powered by DealNinja”, “Brought to you by DealNinja”, “You’ve received a premium offer from DealNinja” or “Ads by DealNinja”.

These ads are aimed to promote the installation of additional questionable content including web browser toolbars, optimization utilities and other products, all so the DealNinja publisher can generate pay-per-click revenue.
When infected with DealNinja the common symptoms include:

• Advertising banners are injected with the web pages that you are visiting.
• Random web page text is turned into hyperlinks.
• Browser popups appear which recommend fake updates or other software.
• Other unwanted adware programs might get installed without the user’s knowledge.

How did DealNinja got on my computer?

DealNinja is an adware program that is commonly bundled with other free programs that you download off of the Internet.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed DealNinja without your knowledge.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this DealNinja adware. Be very careful what you agree to install.
